BQM 305

Recently I have been playing Tengen in combination with Hoshi and San-San (just for some diversity). I have had several games with the following joseki. After Black 7, which should presumably have been at a, White plays at a and Black responds with b. I am not sure whether the result is any good or not. Is this line playable for both or rubbish for one?

LukeNine45: I'm only 4 or 5 kyu AGA but to me this looks quite a bit better for black, at least if it's on an empty board. I can't see a great way for white to exploit the aji of the gap in black's wall (at least not anytime soon), and seems to hurt white's shape? Black seems to have as good or better influence, 12 points or so cash, and as much potential.

AJP: looks fine to me for both. What more did white want to achieve here?

Low

Dieter White pushes once more, next makes a strong and influential shape. Black's position is too low.
IanDavis Thank you,this is a good sequence; I hadn't considered this line.

Normal play

limits Black's development to the top. develops along the left. Compared to the BQM, White has no strong influential position ad Black develops better (higher). As a compensation, White has the initiative but I think she is happy to yield it for the previous diagram.
